My bad - but I do not have time to look into it now.
Too much painting/moving stuff - sorry!

If the driver-core folks could add this patch to their tree to that
changeset, I'd appreciate it. :)

Yep, OK.

Seriously, though the sparc64 allmodconfig has been broken by this for
two days and we really don't want any deliberate bisection breakage if we
can avoid it.

I have not looked into it yet. But I assume this is a merge issue.
sparc-next.git is OK
kbuild-next.git is OK

But when merged we break sparc64.
So I need to feed David a patch so I do not break it with kbuild-next.git,
or I need to do something in kbuil-next.git to avoid the breakage.

I will sort it out in the weekend.

linux-next: sparc64 build failure

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1705 bytes --]

Hi Dave, Greg,

Today's build of linux-next (sparc64 defconfig) failed like this:

arch/sparc64/kernel/pci.c: In function `of_create_pci_dev':
arch/sparc64/kernel/pci.c:412: warning: passing arg 1 of `sprintf' discards qualifiers from pointer target type
make[2]: *** [arch/sparc64/kernel/pci.o] Error 1

This was caused by commit bd24b944eb93549b1ca5becbf27c7373504f7eed
("driver-core: prepare for removal of 20 char limit from struct device")
from the driver-core tree which made pci_name() return a "const char *".

I have applied the following patch.

Greg, it would really help if a version of dev_set_name() was created
early ... like in Linus' tree now?

I'm trying to do that right now, but it's causing a little oops at boot
time that would not be nice to introduce so late in the game :)

We're working on it.

It's wierd that we broke the build like this, I'll work to merge this in
so that it isn't broken.

It broke the build because arch/sparc64 is (mostly) built with -Werror.

Sorry, no, I realized that, I was confused as to why a warning was
created here.  Turns out that pci_name() was being changed to a const
string, and the compiler was rightfully saying that we can't be using
that for an assignment.

I've fixed it up correctly in my latest tree, which you should have
already.

thanks,
